    • Excellent exhaust
It's Flowmaster so you know it's top of the line. Gave my 2001 Jeep Cherokee a very awesome sound. It sounds almost like a V8 now and I love it. If you're thinking about getting this, just do it. You won't be disappointed

    • Great quality muffler.
Replaced the original muffler on a 96’ XJ. The flomastet fit great and sounds great. I removed everything including the Cat from the rig, disassembled it and replaced the parts back on the truck. Aligned the Cat, flomaster and tailpipe. tacked it all up with the mig. Once I was sure everything was aligned and had clearance I removed it all again and securely welded it up. Only clamp is from head pipe to Cat. And that’s tacked just Incase. About 3 hours install. Sounds great, not loud but low rumble. Freeway to trail very happy with replacement. Suggestion. If your tooled up, air chisel, grinders, welder, pretty straight forward job. If not drop the $100 and let the muffler shop replace it. My only regret is I didn’t replace the Cat with a flomaster at the same time. I would also suggest weld the unit together. Off road vehicles high center a lot, hate to loose the exhaust assemble because a clamp failed. Quality of the muffler was as expected, excepltioal. ... show more

    • Review on durability and sound
This muffler has lasted for years. My old ones always tore open on rocks and deteriorated from the heat. This one seems to hold up to everything I can throw at it! I had a u joint blow at about 40mph 2 years ago and the driveshaft beat the muffler hard. It dented it but did not puncture (I still run it to this day) Even the mechanic at the muffler shop said “this is twice the muffler than the others” Sound: I have this on my 2.5L Wrangler and I feared that I would sound like a ricer with it, but it sounds nothing like that. It makes my Jeep louder and adds bass to the engine (I do have a few parts to my exhaust system removed to free up to flow, which makes it louder than usual). It likes to rumble on idle and picks up bass at about 2,000 RPM. It's loudest point is at about 2.5-3k RPM (most bass), then it starts to quiet down a little when you go up into high RPM. ... show more

    • Works and Fits as it Should
This went on fairly easily with clamps. I have a 1980 F100 6 cylinder. I was hoping this would give it a little more bark. It did not do this. It is as quiet as ever. If you don't have a V8, I'd save your cash and get a cheaper/regular muffler.

    • Nice sound!
I installed this on my 02 Jeep Grand Cherokee with the straight 6. It has a nice rumble too it but still quiet enough cruising down the highway that the sound doesn’t get in the way of a conversation. I welded it in place. But a couple clamps could work well too if welding wasn’t an option. It does require a little custom fitting though of course. ... show more

    • Absolutely love it
Flowmaster has always been #1 in its the industry. This Super 44 has a great rasp and throaty. Not quiet as loud as the 40 and not as deep as the super 40. I love it. If you’re considering it, go for it! You will be happy.. I’ve had them all and glad I went with the 44. Not sure if it really adds HP but it sure feels and sound strong as a beast! I got this Super 44 on my 4.0 Jeep Wrangler ... show more

    • 1990 Jeep XJ
Pretty much the same voicing and volume level outside as the Original 40 Series I replaced but with a slightly deeper tone and inside it isn’t too far off from an oem muffler; really pretty pleasant. Windows up and cruising down the highway I have noticed very little to no droning. Best I can compare it to would be a ballsier 40 Series Delta Flow. Now I’m noticing other wind noise, squeaks, and rattles. ... show more
